“The [Vegas] performances won’t be simple—they’ll be a massive party from start to finish,” says Spears. “And to pull this off, I have to be in top condition and running at full speed.”

Spears has been upping her cardio and yoga in preparation for the big show. The mother of two also follows the Nutrisystem diet, which consists of a shake for breakfast and lunch plus a dinner of protein and veggies.

We’re still waiting for an official concert announcement, but local newspaper the Las Vegas Sun reports that Brit Brit will be taking up residence at Planet Hollywood. Rehearsals allegedly began as early as last fall and ticket sale dates will most likely be revealed within the next 20 days.
